在delphi下,通过并口对外控制设备,包含全部源代码.

这是校验位打孔重传的源程序，现发上来供大家学习借鉴。-This is a parity bit punch Retransmission source, fat is up for all to learn from.

载波同步是QPSK信号相干解调的一项关键技术。-Carrier synchronization signal coherent QPSK demodulation is a key technology.

基于matlab实现的OFDM系统中的16QAM子系统-Matlab implementation based OFDM systems 16QAM Subsystem

使用串口控制的一个VC源程序，不使用控件进行通讯。直接使用API调用-use of a serial control VC source, the non-use controls communication. Direct use of API calls

这是个点对点的交流工具，而且容许你在同一时间同步和一个人进行相互聊天和相互传输文件-This is a peer-to-peer communication tools, but at the same time allow you to synchronize and a person to chat with each other and transfer files

主要是Java串口通信的例子,完成了java串口的监测,和多个串口之间的通信

建立管道服务器、客户端实现双向通信，消息实行队列机制。

移动通信基本知识:从通信网的角度看，移动网可以看成是有线通信网的延伸，它由无线和有线两部分组成。无线部分提供用户终端的接入，利用有限的频率资源在空中可靠地传送话音和数据；有线部分完成网络功能，包括交换、用户管理、漫游、鉴权等，构成公众陆地移动通信网PLMN。从陆地移动通信的具体实现形式来分主要有模拟移动通信和数字移动通信这两部种。-Basic knowledge of mobile communications: From the perspective of communication networks, mobile networks can be seen as an extension of wired communication network, which is both wireless and wired components. Part of user terminals to provide wireless access, frequency of use of limited resources in the air and reliable transmission of voice and data wired part of the completion of network functions, including switching, subscriber management, roaming, authentication and so on, constitute a public land mobile communication network PLMN. From land-based mobile communications to the specific forms of the main points have analog and digital mobile communications that two kinds of mobile communication.

多用户检测（cdma系统），大家可以学习一下-Multi-User Detection (cdma system), everyone can learn about

本程序使用VB语言编程，使用WinSock控件完成的点对点（P2P）聊天和文件传输程序。可以实现两台机器间互发消息，并且有聊天和文件传输记录，安全可靠。-procedures for the use of the VB programming language. Use Winsock Control to complete the peer-to-peer (P2P) file transfer and chat procedures. Can be achieved between the two machines each other copies, as well as chat and file transfer records, safe and reliable.
